FOURTH-POINT SUPPORT.

Application filed October 11, 1924. Serial No. 743,133.

This invention relates to new and useful improvements in fourth point supports for brake beams and the objects ofthe invention are to provide a support consisting of two separable members arranged to encircle the brake beam, one of said members being adapted to be quickly and easily detached so as to provide ready access to the brake beam for installation or repair -purposes.

Further objects of the invention are to provide simple and effective means for interengaging the outer ends of said support members, thereby locking the removable member against displacement.

With these and other objects in View, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which' Figure 1 is a side. 'elevational view of the preferred form of the support.

Fiigure 10 is a horizontal cross section opposite ends of said members being spaced I from each otner and in fixed relatlon with a car truck part. The lower member. which forms the track for the'forward end of the brake beam is made removable so that it can be readily detached and mo ved out of the Way when installing or repairing the brake and also to permit'replacementfof said track member when worn or damaged;

sion member 12 of the brake beam. treme end 19 of member 17 is bent to lie flat Referring by numerals to the accompanymg drawings, 10 indlcates a car truck part, such as a spring lank, 11 indicates a com pression member or rear end of the brake a suitable distance beyond the tension mem ber 12. A lower or track member 17 has its inner or rear end 17 slidably positioned in a seat formed by a bracket 18 which is secured to the un erside of the spring plank. Member 17, after leaving the seat, drops. downwardly as at 17 in order to space it from the spring plank and extends outwardly under the brake beam, being provided with an inclined track portlon 17 whichis slidingly engaged and supports ten- The exagainst the underside-of the end of supportmg member 14 andis locked thereto by a bolt and nut or other suitableattaching device 20.

The end of member 14 is provided with an aperture 21 for receiving-the bolt-and member 17 is provided with a longitudinallydisposed slot 22 through which the-bolt passes,

' said slot permitting automatic adjustment'of the track member so that the latter may be properly seated 'and accommodate itself to the-brake beam, and any inaccuracies in the proportions of the members being also thereby taken care of. The length of the slot is less than the length of portion 17 so that the latter cannot be accidentally unseated but at the same time permitting sliding movementof the outer end of said track member with respect to said supporting member. After member 17 is in proper position, the nut and bolt connection is locked'against accidental disengagement by a pin 20 or in any other suitablev manner.

In the formshown in Figures 3 and 4, a supporting member, 241- has'i-ts extreme end bent downwardly as at 2 1" and formed therein i's-a slot 25 for thereception of the reduced end'26 of a track member 27. A cotter pin 28 is seated in the projecting portion of: end

26 and prevents thewithdrawal thereof from the slot in the end 24. The reduced outer end 26 of the track member is of sufficient length to permit sliding movement of said end relative to the supporting member, it being necessary for saidtrack member to have one end slidable in order to utilize the resiliency of said member.

In the preceding forms, both the supporting member and the track member are made flexible. However, if desired, the supporting member may be formed rigid as disclosed in Fi ures and 6. In this form, which is similar in construction to thetorms previously described, the supporting mem ber 29 is formed rigid and is carried by spring plank l0 and has its outer end bent downwardly for engaging one end 26 of track member the opposite end being secured to the spring plank.

In the forms shown in Figures 7 to 9, in= elusive, the extreme end 30 of end supporting member 31 is provided with an aperture 32 in which is adapted to be seated a clownwardly extending tongue or projection 34 formed on the rebent portion 35 of a track member 36. In this form, when the members are assembled together, the rear end of the track member is held in a seat formed on the underside or" the spring plankand the forward end thereof is interlocked with the apertured end of the supporting member by I means of tongue 34 occupying aperture 32.

To remove track member 36 from position,

the rebent portion 35 is pried away from the end 30 so as to bring tongue 34 out of engagement with aperture 32, whereupon track member 36 can be withdrawn from its position. Aperture 32 is of suiiicient length to permit the rebent end to have sliding movement-relative to said end 30. The tongue 3st occupying said aperture prevents disengagement of said ii'iterlocked ends.

' A support'ot my improved construction is very simple and has its track portion formed detachable so that it'can be easily removed from its position. The supporting member which is secured to the spring plank has its outer end adapted to enter into interlocking engagement with the corresponding end of the track member, thereby holding said track member against displacement. The resilient track member is slidably or yieldingly supported between said supporting member and said'car truck part, preferably by having one or both of its ends in sliding interengagement with the respective support or supports. Thus any longitudinal movement of said track member, which movement is dueto the resilient nature of said track' preferred forms of my invention, it will bereadily understood that minor changes in the construction and. arrangement of parts of my improved support can be made and substituted for those herein shown, without departing from the spirit of my invention.
